. To all whom t mai/concern;

Be it known thatL'FRANK MrBiirDLnm a "citizen of the lUnited States, residingat Ashland, inthe county oCla'rk and State of Kansas, havefinvented` new and useful Improvements in Spring-Wheels', of which,

the following is a specification.

for use onjautonio'biles and in other places where side thrusts must be avoided and to construct the sainey in such a 'manner thaty it will be adapted. to either pneumatic or cushion tires;

' Thisobject Iaccomplish bythe construc-V .tion hereinafter more fully` described and claimed, and as vshown in the ydrawings wherein,-

Figure l is a side elevation of a portion of this wheelwith some of the springs in place. Fig. 2 is an enlarged cross section through one side of the saine on the-line 2-#2 v`of Fig. 1. Fig. Bris a sectional detail showing another forni of tire. jFig4 is a perspective detail of one of the springs.

In the drawings the letter H designates the hub, S the spokes, F the felly, and T the tire of a wheel, these parts being of the l usual orof any approved construction and 30.

forming no part of the present invention. It is mypurpose to employ with such a. wheel a peculiar shape of springs between. the fe'lly andthe rimwhere'on thtii'eis mounted, and in order to carry outn the, idea* I modify or amplify the detailsloffconstruc?' tion of these parts as will now be described.

' The' felly F is by preference curved on its outer face as scen at 5, and over the same lies a, facing strip -6 which is by preference a channeled steel band curved to conform with V the felly. The inner rim 7 is by preference a channeled steel band curved in cross section and provided with flanges 8 alongits 'edges which bear on shoulders 4. 'The outer rim 7 is spaced from the inner rim, the space being provided .for the reception of the springs best seen in Fig. 4t, and their curved adjacent faces serving to deflect outward the mud and dust which might otherwise accumulate therein. At various points around the wheel there are disposed uponl said curved faces malleable blocks 9 whose cuter faces are curved to conform. with the curved faces of the strips and whose inner "-1'5faces vare flat, and between these blocks are 4. located S-shapecl springs 10 whose extremities are bolted to the flat faces of the 'blocks as atll and 12, 'there being by preference two of the bolts 1l to each inner end ofthe I through the .block and the rim at that point.. This invention isa spring wheel, and the 'object of the same 'is to. produce vsuch a wheel opiposite eiids of the latter, and at the'riglit e of the top of this view I have shown one bolt '11 in'verted so that its headl sta-nds' within the felly F and its nut inside the ,washer plate 13, therefore illustrating the fact that it might lvbe possible to reverse the position of the bolts. 4Obviously the washer plates could be omitted entirely if desired, although I consider theiruse preferable because they strengthen the structure. I prefer to make these yspriifigs each of one-sixgive them the desired curvature so as to 0ccupy the siace between any two-oppositely disposed blocks 9, although of course these dimensions are` susceptible of considerable change without departing from the spirit of my invention.

J The tirebed 2O is shown in Fig. 2 as a flat plate or strip having flanges 28 on its edges which project radially outward and stand in alinement with the flanges 8 along the edges of rim 7,-and just vinside these flanges 28 are other flanges 27'projecting radially'inward and which therefore stand just inside said flanges 8 so as to make a close connectio therewith. Through this bed and prefera ly also through the flanges 27 thereof are passed radial rivets 0r bolts 26 by means of which thebed is detachably connected with the rim 7. If saidbed is a flat plate as shown in Fig. 2, there is a space `25 left between it and the curved or dished outer face of the rini 7, but it is quite possible to gine the bed another configuration to adapt it to the shape of the tire` -T which is to be placed thereon. This tire-ciriFig. 2 is shown as made up of two 'cushion `tires sta riding side by side, and each comprising about three-quarters of a circle; and in Fig. 3 il. have shown a single cushion tire T having'a corrugated .face 24 which will prevent `slippiiig or skiddingperhaps as well as a.'

3 teenth inch thickness, about three inches in E width, and of such length as is necessary yto The size of the latter is of course immaterial and the thickness and width of the .material ofv which the springs is composed is also dependent upon the strength that the tinished Wheel must have. As the'- latter revolves and the Weight of the superstructure is thrown upon the springs at the bottom, they compress While those at the top expand, and simultaneously those at the sides of the Wheel must deflect a little out of a. true radial line as will be understood. This action takes place constantly during the rotation of the wheel and is noiseless and automatic, and when an obstruction such as a stone is struck the springs at the bottom Compress to a greater extent and the jar of passing over the obstruction is not Communicated to the superstructure.

' An extremely important feature of my invention is the fact that in rounding curves or When a side thrust is thrown .upon this Wheel its outer member will not be defiected out of the plane of its inner member and the spokes'because the springs are rather Wide and are .connected at several points at their extremities With both the facing strip '6 and the rim 7. Obviously the bolts l1 through the felly F must stand-at either side of the tenon Where the outer end of the spoke S joins said felly, but the bolts l2 which connect the outer end of the springs with the rim 7 can be three in number as shown in Fig. 2 because 'there is no such tenon at this copiesof this patent-may be obtained for sides of the wheel. lVhen the latter is used,

however, its flange 27 fits neatly Within the flange 8 along the edge of the rim as seen in Fig. Q so that there is no possibility of lateral movement of the bed 2O with reference to the rim 7. As above stated, the exact shape and character of the tire is inimaterial to this invention` as is` also its manner of fastening within the tire bed 2O or Within the curve-d side ofthe rim 7.

What is claimed as neiv'is:

l. In a spring Wheel, the combination With the felly; of an inner rim secured to the felly, an outer rim including a channeled portion adapted to receive a tire, and a fat:-

ing strip secured to the channel portion and having a convex surface, blocks having 6G curved faces conforming to the convex surfaces of said stripr and secured to the strip, and springs connecting said blocks with said' inner rim.

2. In a spring Wheel, the combination strip dished in cross section and having" outwardly projecting -flangesat its edges, and sprmgs between the felly and strip; of a tire bed h'avin'g on its inner face fianges projecting inwardly and adapted to pass inside those on the rim, bolts passing through said bed, fianges. and rim, and a tire secured upon the outer face ofv said bed.

In testimony whereof I laffix my signature in presence of tivo Witnesses.
